Rimland theory
Also called: Spykman's rimland · Topic: Human Geography: Nature, Scope and Approaches · NCERT: Beyond NCERT
Meaning
The rimland theory says that world power lies in the rimland. The rimland is the coastal belt around Eurasia, running from western Europe through the Middle East and South Asia to East Asia. Nicholas Spykman, an American thinker, set it out in The Geography of the Peace (1944). He was replying to Mackinder's heartland theory, which placed power in the inner land of Eurasia. Spykman argued that the rim matters more because it joins land power (armies and land routes) with sea power (navies and ocean trade). His formula was: "Who controls the rimland rules Eurasia; who rules Eurasia controls the destinies of the world." The theory shaped the Cold War policy of containment, which meant ringing the Soviet Union with allies along the rim.
Example
India lies on the rimland. It sits in South Asia, between the Himalayas to the north and the Indian Ocean to the south. This position makes India important in today's Indo-Pacific strategy and in the contest over China's Belt and Road routes.
Don't confuse with
- Heartland theory: Halford Mackinder (1904; revised 1919) placed power in the inner "pivot" of Eurasia, running roughly from the Volga to eastern Siberia, where sea power cannot reach. Rimland theory places power in Eurasia's coastal rim instead.
